- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 11 terminating modules (8 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function (((long long) -2 * i) + 3) and consists of 3 locations. One deterministic module has affine ranking function null and consists of 4 locations. 8 modules have a trivial ranking function, the largest among these consists of 27 locations.
